The water pressure should not be over the rated pressure. The washing time is decided by the filtering effect. 8. How to do to achieve a better dehydration effect? To realize a better dewatering effect, the cakes can be blown by compressed air and the method is the same as the above. The compressed air also can be fed in via a feeding hole.

The general rule for cake washing is 1.5 gallons per hour per square foot of filter area. This is considered to be an average washing flow rate, however the actual flow rate depends largely upon the cake density and the degree of chamber fullness. Cake washing can vary from an average minimum flow rate of ~ 0.50 gallons per hour per …
